Unit operating instructions IT 6108 Infrared Transmitter Features The control console is be able to transmit up to eight sound channels (FM) to different carrier frequencies, Every transmitting channel can be separately switched on. Transmitting channels on which no interpreter sound is present automatically transmit the original sound All transmitting channels can be listened to directly at the transmitter via a receiver (IR test diodes). Up to 20 DIS series IR15-xx Infrared Radiators can be directly linked up. Cascade coupling feature for additional languages Description The IT 6108 Infrared Transmitter is designed in a standard 2HE 19 box. The IT 6108 Infrared Transmitter is part of the DCS6000 which serves the cordless sound transmission with the aid of infrared light. The sound signal is thereby converted into a frequency-modulated infrared light signal and emitted via transmitting diodes. With the DIS series of IR15-xx Infrared Receivers the light signal is recorded and re-converted into a sound signal, which can then be heard on a set of headphones. Different frequencies of up to 8 channels can be transmitted simultaneously with an FM narrow band modulation. The IT 6108 Infrared Transmitter is used for modulating the sound signals on the different carrier frequencies and for amplifying. The IT 6108 Infrared Transmitter is designed in a standard 2HU 19 box. Seven interpreted languages and the original or eight interpreted languages can be transmitted. Two or more IT 6108 can be cascade coupled for adding more interpreted languages to the system. User Controls, indications & connectors Front plate controls The IT 6108 Infrared Transmitter features the following controls and indications: Power ON SWITCH On the front right-hand side of the IT 6108 there is a POWER switch for switching power ON. Power ON led On the front right-hand side of the IT 6108 there is a green POWER ON LED which shows whether the unit is switched on. Test LED (3x) These LED s are used for testing the IR transmission on the front of the IT 6108, by using an IR15-xx IR-receiver Channel setting elements The operating elements of the eight infrared channels are located on the front side of the console. Each infrared channel consists of the following: AF LED This LED is flashing if the original voice or interpreter voice is present at the channel. ON LED 7
This LED lights if the channel is switched ON by use of the DIP switch DIP switch This DIS has 4 individual switches: 1. ON / OFF switch. If set to ON this channels is transmitting the channel selected by the Rotary Switch. 2. Not used 3. Not used. Has to be in ON position always 4. Frequency band switch. In ON position; CH O to CH 13. In OFF position CH 14 to CH29. When using with IR15-06 and IR15-12 this switch has always to be in ON position. Rotary Switch This switch is used for channel setting. This can be used to set the channels independently of the frequency band switch. Connectors The IT 6108 contains the following sockets on the rear side: Power connector Connection for main power with an integrated ON / OFF switch. Input (A-H) Eight XLR sockets feeding the analogue sound to the transmitter.

System settings The output channels are each set by use on the DIP Switch and the Rotary Switch as shown in the following figures. The channel setting are normally done that the first channel (A) is set to CH 0 (original) the next (B) to CH1 and so on. Setting CH 0 to CH 13 For using CH 0 to CH 13 set the DIP switch as shown in the figure. Important: Do not set the rotary switch to position B at any of the rotary switches where the DIP switch is set for channel 0 to 13, as it will make the transmitter not working Setting CH 14 to CH 29 For using CH 14 to CH 29 set the DIP switch as shown in the figure. For each of the 8 channels set the wanted Channel Number by turning the Rotary Switch to the wanted channel. The numbers on the Rotary switch corresponds to a Channel Number as show in the figure below. If a channel is not in use set the DIP switch for that channel to OFF. Important: No channels on any IT 6108 in the system must be set to the same Channel Number For each of the 8 channels set the wanted Channel Number by turning the Rotary Switch to the wanted channel. The numbers on the Rotary switch corresponds to a Channel Number as show in the figure below. If a channel is not in use set the DIP switch for that channel to OFF.
